'7 Claims.

This invention has reference to cotton picking devices and has as its primary object the provision of a device which may be readily suspended from the shoulder of the cotton picker or laborer and: easily manipulated by him for picking the cotton.

The invention consists in a novel combination and arrangement of elements providing for a compact and efficient structure and of a weight as not to be too burdensome for a person to carry.

The invention together with its numerous objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawings wherein is illustrated a preferred embodiment of the invention; V

It is to be understood at the outset that it is in no wise intended to restrict the invention to the precise details of construction, combination and arrangement of elements as herein illustrated and described, other than may be necessary to meet the requirements of the prior art and scope of the appended claims.

' In the drawings:

Figure 1 is a perspective view of the device illustrating the manner of suspending it from the shoulder ofa person;

' Figure 2 is a top plan view of thedevice,

Figure 3 is a fragmentary view partly in section and partly in elevation showing the mechanism for revolving the tool equipped shaft of the device.- a

Figure 4 is a vertical transverse sectional view through the device. 7

' Figures 5 and 6 are sectional views taken respectively on the lines 5-5 and 66 respectively of Figure 2, and

Figure 7 is a perspective view of the picking tool.

Referring to the drawings by reference numerals it will be seen that the device comprises arelatively narrow elongated frame 5 having a broad fiat end portion 6 and spaced parallel side members 7 connected at one end to the portion 6 of the frame. Brackets 8, 9 are mounted on one of the side bars 7 and journalled in the brackets are rollerslO, '11. On the other of the side bars '7 is mounted abracket 12 in which is journalled a shaft l3 provided with a hand crank 14. On the free end of the shaft between the side members 7'7 there mounted a disk 15 provided on one face with a semi-circular hump 15 that is en-V' gageable with the roller 10, and a relatively short arcuate' hump 16 arranged inwardly of the hump 15 and engageable with the roller 11.

Slidably and rotatably mounted in the frame 5 and supported by the brackets'8, 9 and a bracket 17 is a shaft 18 that is non-circular in cross section. Rollers 10, 11, have hubs provided with noncircular bores which receive the shaft lS whereby the rollers are mounted on the shaft 18 for ro tative movement therewith. On the shaft 18 between sides of the bracket 17 is aeollar 20 relative to which the shaft 18 is slidable. v 1

On the free end of the shaft 18 there is provided a suitable picking tool 21 and the samezmay be, as shown in Figure 5 integral with the shaft 18, or may be a separate tool as shown in Figure 7 and designated by the reference numeral 21a In this. connection suitable means will of course beprovided for detachably securing thetool 21a totheshaftl8. I v i 1 The tool equipped end of the shaft 18 operates through a cylinder 22 fixedly supported by brackets 23 between the ends of the side-bars 'l remote from the frame end 6.

As shown in Figure 5 the cylinder 22 is provided with a discharge opening 24 through which the cotton passes into a dependingspout 25-that accommodates the mouth of a bag 26'which is secured at said mouth to the side bars 7 as at 2'7. The bottom or closed end of the bag is-sup or-ted fromone side of theframe memberfi by suitable hook and eye means 28. The bag 6 is of thetype shown in the drawings and is provided with a suitable closure flap 29, For reciprocatingthe shaft 18'there is provided a lazy tongue structure 7'30 anchored at one end to a crossbar 31 secured'between the frame bars 7. At its other end the lazy tongue 30 is connected to a slide 31 of suitable construction mounted between the bars '7 for sliding movementrelative thereto.- Rotatably mounted in the slide 31 and anchored to the-shaft 18 asat32 is a collar 33 as will be clear 1 from a study of Figurefi. For actuating the lazy tongue 30 there is provided a pitman rod- 3 1 that is eccentrically mounted on the disk 5 as at 35.

For removing thetcotton 'on the tool 21 when the tool is drawn inwardly of the cylinder 22 there is provided at the inner, end of the cylinder 22 a block 36 the inner end face 37 of which cooperates with the tool 21 in a manner thought apparent to remove the cotton from the tool.

From the description of the invention thus far it will be seen that byoperating the handle 14 the disk 5 is rotated in a clockwise direction. to engage the hump 15' with the roller 10 torotate the shaft'l8 while at the-same time through the medium of the pitman rod 34 and the lazy tongue 30 the shaft 18 will be projected outwardly with block 36 within the cylinder and continues inwardly of the socket 38 provided in said block.

to accommodate the tool, the cotton on the tool will engage the inner face 37 of the block "and will be forcibly removed fromthe tooltofall through the spout 25 and into, the bag. 26.

For suspending the device from the shoulder of the person operating it there is provideda shoulder strap 39 that is connected at one end throughthe medium of springs 40 with intermediateportions of the frame side members '7. Y The other end of the strap'39 is connected through the medium'of a spring 41 with one end of a handle '42 that is secured to the end 6 of the frame as at 43. As shown in Figure 1 the handle 42 will be gras'pedby one-hand of the operator of the device for st'eadyingthe device, while the other hand of the operator is used for controlling operation of the device.
